Disable head line when using "Guide on" navigation

Hi,
is it possible to disable the "head line" (with target nme, direktion, distance) when I select a target and using "Guide on" to have a line from my location to the target?
I only want to have the line in the map,
but when in Landscape-mode there is to many place neede for this head line on the top.
If not possible to diable, is it possble change the transperancy ?

(if not, can I create a feature request for this ?)
